I've noticed when my windows are down and I turn the wheel left or right I can hear a electrical switch "tick". At the same time I will see the RPMs jump just a little to compensate for steering as I slightly turn the wheel.

Even if your sitting in park with the engine running simply turn the wheel a little left or right and I get the "tick" every time! I don;t expect it to be silent. But I've not owned a car that had such a pronounced sound from a steering pressure switch.

Are your switches noisy as well?

My transmission also "ticks" alot. Everytime I come to a stop at exactly 10mph. It sounds similar to the steering noise but I can tell they are different locations.
